Though from the time of King Egbert, in 802, the Kings of the West-Saxons were monarchs of all England, yet several kings reigned in certain parts after that time, in some measure subordinate to them. One Offa was King of the East-Angles, who, being desirous to end his days in penance and devotion to Rome, resigned his crown to St. Edmund, at that time only fifteen years of age, but a most virtuous prince, and descended from the old English-Saxon kings of this isle. The saint was placed on the throne of his ancestors, as Lydgate, Abbo, and others express themselves, and was crowned by Humbert, Bishop of Elman, on Christmas Day, in 855, at Burum, a royal villa on the Stour, now called Bures, or Buers. Though very young, he was by his piety, goodness, humility, and all other virtues, the model of good princes. He was a declared enemy of flatterers and informers, and would see with his own eyes and hear with his own ears, to avoid being surprised into a wrong judgment, or imposed upon by the passions or ill designs of others. The peace and happiness of his people were his whole concern, which he endeavoured to establish by an impartial administration of justice and religious regulations in his dominions. He was the father of his subjects, particularly of the poor, the protector of widows and orphans, and the support of the weak. Religion and piety were the most distinguishing part of his character. Monks and devout persons used to know the psalter without book, that they might recite the psalms at work, in travelling, and on every other occasion. To get it by heart St. Edmund lived in retirement a whole year in his royal tower at Hunstanton (which he had built for a country solitude), which place is now a village in Norfolk. The book which the saint used for that purpose was religiously kept at St. Edmundsbury till the dissolution of abbeys.

The holy king had reigned fifteen years when the Danes infested his dominions. Hinguar and Hubba, two brothers, the most barbarous of all the Danish plunderers landing in England, wintered among the East-Angles; then, having made a truce with that nation, they in summer sailed to the north, and landing at the mouth of the Tweed, plundered with fire and sword Northumberland, and afterwards Mercia, directing their march through Lincolnshire, Northamptonshire, and Cambridgeshire. Out of a lust of rage and cruelty, and the most implacable aversion to the Christian name, they everywhere destroyed the churches and monasteries; and, as it were in barbarous sport, massacred all priests and religious persons whom they met with. In the great monastery of Coldingham, beyond Berwick, the nuns, fearing not death but insults which might be offered to their chastity, at the instigation of St. Ebba, the holy abbess, cut off their noses and upper lips, that appearing to the barbarians frightful spectacles of horror, they might preserve their virtue from danger; the infidels accordingly were disconcerted at such a sight, and spared their virtue, but put them all to the sword. In their march, amongst other monasteries, those of Bardney, Crowland, Peterborough, Ely, and Huntingdon were levelled with the ground, and the religious inhabitants murdered. In the Cathedral of Peterborough is shown a monument (removed thither from a place without the building) called Monks'-Stone, on which are the effigies of an abbot and several monks. It stood over the pit in which fourscore monks of this house were interred, whom Hinguar and Hubba massacred in 870. The barbarians, reeking with blood, poured down upon St. Edmund's dominions, burning Thetford, the first town they met with, and laying waste all before them. The people, relying upon the faith of treaties, thought themselves secure, and were unprepared. However, the good king raised what forces he could, met the infidels, or at least a part of their army near Thetford, and discomfited them. But seeing them soon after reinforced with fresh numbers, against which his small body was not able to make any stand, and being unwilling to sacrifice the lives of his soldiers in vain, and grieving for the eternal loss of the souls of his enemies, who would be slain in a fruitless engagement, he disbanded his troops and retired himself towards his castle of Framlingham, in Suffolk. The barbarian had sent him proposals which were inconsistent both with religion and with the justice which he owed to his people. These the saint rejected, being resolved rather to die a victim of his faith and duty to God, than to do anything against his conscience and religion. In his flight he was over taken and surrounded by infidels at Oxon, upon the Waveney: he concealed himself for some short time, but, being discovered, was bound with heavy chains and conducted to the general's tent. Terms were again offered him equally prejudicial to religion and to his people, which the holy Icing refused to confirm, declaring that religion was dearer to him than his life, which he would never purchase by offending God. Hinguar, exasperated at this answer, in his barbarous rage caused him to be cruelly beaten with cudgels, then to be tied to a tree and torn a long time together with whips. All this he bore with invincible meekness and patience, never ceasing to call upon the name of Jesus. The infidels were the more exasperated, and as he stood bound to the tree, they made him a mark wantonly to shoot at, till his body was covered with arrows like a porcupine. Hinguar at length, in order to put an end to the butchery, commanded his head to be struck off. Thus the saint finished his martyrdom on the 20th of November, in 870, the fifteenth of his reign, and twenty-ninth of his age; the circumstances of which St. Dunstan learned from one who was armour-bearer to the saint and an eye-witness. The place was then called Henglesdun, now Hoxon, or Hoxne; a priory of monks was afterwards built there which bore the name of the martyr.

The saint's head was carried by the infidels into a wood and thrown into a brake of bushes; but miraculously found by a pillar of light and deposited with the body at Hoxdon. These sacred remains were very soon after conveyed to Bedricsworth, or Kingston, since called St. Edmundsbury, because this place was St. Edmund's own town and private patrimony; not on account of his burial, for in the English-Saxon language signified a court or palace. A church of timber was erected over the place where he was interred, which was thus built according to the fashion of those times. Trunks of large trees were sawn lengthways in the middle and reared up with one end fixed in the ground, with the bark or rough side outermost. These trunks being made of an equal height and set up close to one another, and the interstices filled up with mud or mortar, formed the four walls, upon which was raised a thatched roof. Nor can we be surprised at the homeliness of this structure, since the same was the fabric of the royal rich abbey of Glastonbury, the work of the most munificent and powerful West-Saxon kings, till in latter ages it was built in a stately manner of stone. The precious remains of St. Edmund were honoured with many miracles. In 920, for fear of the barbarians under Turkil the Dane, in the reign of King Ethelred, they were conveyed to London by Alfun, bishop of that city, and the monk Egelwin, or Ailwin, the keeper of this sacred treasure, who never abandoned it. After remaining three years in the Church of St. Gregory, in London, it was translated again with honour to St. Edmundsbury in 923. The great church of timberwork stood till King Knute, or Canutus, to make reparation for the injuries his father Swein, or Sweno, had done to this place and to the relics of the martyr, built and founded there, in 1020, a new most magnificent church and abbey in honour of this holy martyr. The unparalleled piety, humility, meekness, and other virtues of St. Edmund are admirably set forth by our historians. This incomparable prince and holy martyr was considered by succeeding English kings as their special patron, and as an accomplished model of all royal virtues. The feast of St. Edmund is reckoned among the holidays of precept in this kingdom by the national council of Oxford in 1222; but is omitted in the constitutions of Archbishop Simon Islep, who retrenched certain holidays in 1362.
